title: The CRP-range latex test. A new method for the semiquantitative determination of C-reactive protein in serum.
abstract: A new CRP Range Latex Test is described which allows by testing two serum dilutions to classify the CRP content semiquantitatively into four concentration ranges (0 - 1 mg/dl, 1 - 4 mg/dl, 4 - 16 mg/dl and 16 - 64 mg/dl). Sera of 30 patients with rheumatic diseases and of 30 control persons without inflammatory or degenerative diseases were investigated in the CRP Range Latex Test and by radial immunodiffusion. The results were compared. A good agreement between the two methods could be demonstrated.
